The active log is 128 GB. I don't want it to raise to 512 GB, recovering 128
GB takes 4 hours, so recovering 512 GB takes 16 hours !

Active log, archive log and database are all stored on SVC + FlashSystem 840.

We noticed that the 6 Power7 cores are 100% used so we switched to client
dedup to distribute the load.
In the meantime, we lowered the versions, reclamation and dedupe identify
processes so the load is less on the TSM server.
We are also redirecting the larges backups to tape to take some of the load of
the disks.
